1/f noise in the Two-Body Random Ensemble
A. Relano, R. A. Molina, J. Retamosa
We show that the spectral fluctuations of the Two-Body Random Ensemble (TBRE) exhibit 1/f noise. This result supports a recent conjecture stating that chaotic quantum systems are c…
Length-dependent oscillations of the conductance through atomic chains: The importance of electronic correlations
Rafael A. Molina, Dietmar Weinmann, Jean-Louis Pichard
We calculate the conductance of atomic chains as a function of their length. Using the Density Matrix Renormalization Group algorithm for a many-body model which takes into account…
Residual conductance of correlated one-dimensional nanosystems: A numerical approach
Rafael A. Molina, Peter Schmitteckert, Dietmar Weinmann +3
We study a method to determine the residual conductance of a correlated system by means of the ground-state properties of a large ring composed of the system itself and a long non-…
